Lost Wax Casting

For thousands of years the lost wax casting technique has been used by industry professionals. Most commonly the technique is used to cast jewellery in precious metals, but if you do your research you’ll discover it was also used to cast the bronze weapons, tools and statues of Ancient Greece and the Renaissance.

So, how does it work? Put simply, an object is modelled in wax, then the wax is replaced with molten metal. Optimum brasses use rubber moulds, created using period original brass fittings to form the waxes. Thanks to the versatility of the lost wax casting technique, it is also possible to cast other materials in order to create a final finished piece in brass.

As specialists in the brass industry, Optimum prides itself on using a brass mix that closely matches that of brass made in the 18th Century, rather than modern brass, which often does not age to the desired colour.
